PX8 is an Open Source Fantasy Console (128x128 pixels) in Rust, by using a cartridge that contains the code/gfx/music. The code could be in Python/Lua, or you could create directly everything in pure Rust by using it as a library.
It is still in development, but it is usable and the main features are: * 128x128 pixels default resolution * Predefined palettes (pico-8, c64, etc), or use any RGB colors * Python 3 / Lua 5.X support for the cartridge without tokens limit * Desktop/Mobile/Browser (Emscripten) support * Controls with dpad + 2 buttons (gamecontroller/joystick support) * Unlimited sprites (8x8) * Map support (128x32) * Editor for the sprite and map data * PX8 format to be able to use your favorite code editor for Python/Lua/Rust * Change the screen definition (128x128, 256x256, WIDTHxHEIGHT) * Screenshot (PNG) / Video recording (GIF) * Pico-8 compatibility + cartridge (P8/P8.PNG) format support * Audio support is in progress
It works on all platforms (Linux/OSX/Windows), in the browser (via Emscripten), and on tiny hardware like Raspberry Pi 2/3.
The console is inspired from the awesome Pico-8, so there is a compatibility mode (not 100%, and it is not the goal of the project) available with Pico-8 console and cartridges (P8/PNG).
The time for each frame is slow (10ms) in the GIF, and doesn't correspond to the speed of the game.

You can get directly the latest version via git:
git clone https://github.com/Gigoteur/PX8.git
cd PX8
Or you can get latest binaries for multiples platforms directly on itch.io: * Raspberry Pi (available) * OSX (available) * Windows (Work in progress) * Linux (Work in progress)
and old binaries could be obtain for free.
You will need multiple things: * SDL2 * python3 * libreadline
Packages for Debian/Ubuntu: * libsdl2-dev * libreadline-dev * libpython3-dev
Please enable the GL Driver (7 - Advanced Options -> Ac - GL Driver -> Yes) via:
sudo raspi-config
Install external dependencies via brew: * brew install python3 * brew install sdl2 * brew install readline
Right now you need to export the DYLDFALLBACKLIBRARYPATH env variable for the python support, e.g: * export DYLDFALLBACKLIBRARYPATH=/usr/local/Cellar/python3/3.5.1/Frameworks/Python.framework/Versions/3.5/lib
The first thing to do is to install Rust, so please go to rustup and follow all instructions.
You could build PX8 with cargo directly, in release mode for example, with the support of Python and Lua.
cargo build --features="cpython lua" --release
By default the resolution will 128x128 but you can change the default values by specifying the values of the env variables PX8SCREENWIDTH + PX8SCREENHEIGHT during the compulation:
PX8_SCREEN_WIDTH=256 PX8_SCREEN_HEIGHT=256
Example:
PX8_SCREEN_WIDTH=256 PX8_SCREEN_HEIGHT=256 cargo build --release
If you want to use the gfx_rs renderer (WIP):
cargo build --features="gfx_rs_renderer" --release
You can force opengl with SDL via the '-o' option:
./target/release/px8 -o ./games/ski/ski.px8
You must follow the following guide to install Emscripten.
You can see example of PX8 + Emscripten in the demos repository. You could also see live example from your browser: * Hello World [Source Code] [Live Demo] * Lua Cartridge [Source Code] [Live Demo] * Cast [Source Code] [Live Demo]
Each pixel can be access from 0 to 128 (or the new defined width/height) :
Player 1: * cursors, Z,X / C,V / N,M
Player 2: * ESDF, LSHIFT,A / TAB,Q,E
System shortcut: * F2: Information debug (FPS, time execution (draw,update), palette name) * F3: Take a screenshot (png) * F4: Take a video (gif) * F5: Save the current cartridge's data (if opened with editor mode) * F6: Switch between editor/play mode (if opened with editor mode) * F7: Switch to the next available palette
You should be able to run it directly by providing the path of the cartridge:
./target/release/px8 ./games/ski/ski.px8
You could run the API demos:
./target/release/px8 -s 4 ./examples/api_demos.py
or some fancy demos:
./target/release/px8 -s 4 ./examples/demos.py
./target/release/px8 -s 4 ./examples/voxel/voxel.px8
./target/release/px8 -s 4 ./examples/pong/pong.px8
./target/release/px8 -s 4 ./games/ski/ski.px8
./target/release/px8 -s 4 ./games/amp/amp.px8
./target/release/px8 -s 4 ./games/terrain/terrain.px8
./target/release/px8 -s 4 ./games/BR/BR.px8
You can edit the GFX in the cartridge by using the specific '-e' option, and alternate between the run mode and the editor with 'F6':
./target/release/px8 -s 4 -e ./games/ski/ski.px8
and you can save the GFX with 'F5'.
With the '-s' option you can change the size of the console, so you can increase it (2/4/8/10).
You can also use the fullscreen option by using '-f' option.
You can add the '-o' option to force SDL to use OpenGL
You could load a PICO8 cartridge file by using the '-m pico8' option to convert the Lua code.
PX8 will call 3 functions, at startup or during the runtime: * _init : Called once on startup, mainly to initialize your variables * _update: Called once per visible frame, mainly to get keyboard input for example * _draw: Called once per visible frame, mainly to draw things on the screen :)
After that you can use the API to do your game. There is no limitation of what you can do in Python or Lua languages.
By default I don't do any modification in the Python or Lua interpreter, so you are free to create threads, load native files, etc
You will be able to find more technical documentation in the wiki
You can create a classical Python program, all you need is to define the previous functions (_init, _update, _draw), and you can import any packages.
```py def init(): px8print("INIT")
def update(): px8print("UPDATE")
def draw(): px8print("DRAW") ```
```lua function _init() print("INIT") end
function _update() print("UPDATE") end
function _draw() print("DRAW") end ```
